Galaxy S3 users have been waiting for quite a long time to experience the latest Android software version as Samsung did not update the device to Android 4.2 and it was still running on the older Android version, 4.1.2, same as the case with the Galaxy Note 2, notes Sammobile.

There is no official information as to why Samsung skipped the Android 4.2, although it internally tested a few Android 4.2 builds for the Galaxy S3 but, never released the update and seemed to have stopped the development midway.
